Microsoft found that a direct connection to one's immediate manager was the biggest factor in effective onboarding.

Judge as of 2022-05-24. True: published Microsoft research (e.g. a WorkLab or Work Trend Index report, or an internal study described by Microsoft) on onboarding or new employees found that connection with one's immediate manager was the single most important factor in good onboarding outcomes. Mostly true: the research shows the manager connection as one of the most important factors (e.g. top-ranked alongside others, or most important for a closely related outcome such as feeling connected or productive), but not explicitly as the single biggest. Mixed: the research finds the manager relationship matters but ranks it as one of several factors with no clear primacy. Mostly false: Microsoft research identifies a different factor (e.g. onboarding buddies or peer networks) as the biggest, with the manager only secondary. False: Microsoft research shows the manager connection is not a significant factor, or no such Microsoft finding exists because the research found something contrary.

Set before the research began.

   “A key finding of their research: When managers played an active role, new employees were 3.5 times more likely to say they were satisfied with their onboarding experience. They were also 1.2 times more likely to feel that they were contributing to their teams’ success.”

   “Microsoft onboarded thousands of new employees during the pandemic. And one clear insight emerged: “The biggest, biggest thing we found is the direct connection to your immediate manager,” Nadella said.”

   “Our research found that after their first week on the job, new hires with buddies were 23 percent more satisfied with their overall onboarding experience compared to those without buddies.”

E1 is a Microsoft WorkLab account, published before the claim date, of Microsoft's own onboarding research. It reports that new employees whose managers played an active role were 3.5 times more likely to say they were satisfied with their onboarding; E3 separately reports that new hires with buddies were 23 percent more satisfied, which is a different measure. Neither source explicitly ranks the manager connection as the single biggest factor, and E3 reports a separate satisfaction effect for onboarding buddies. So the research supports the manager connection as one of the most important factors, but not explicitly as the top one. E2 only repeats Nadella's own statement and adds no independent support.
